  • Spatiotemporal Pattern of Phenology Across Geographic Gradients in Insects
    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2017 Spatiotemporal pattern of phenology across geographic gradients in insects Khelifa, Rassim Abstract: Phenology – the timing of recurrent biological events – influences nearly all aspects of ecology and evolution. Phenological shifts have been recorded in a wide range of animals and plants worldwide during the past few decades. Although the phenological responses differ between taxa, they may also vary geographically, especially along gradients such as latitude or elevation. Since changes in phenology have been shown to affect ecology, evolution, human health and the economy, understanding pheno- logical shifts has become a priority. Although phenological shifts have been associated with changes in temperature, there is still little comprehension of the phenology-temperature relationship, particularly the mechanisms influencing its strength and the extent to which it varies geographically. Such ques- tions would ideally be addressed by combining controlled laboratory experiments on thermal response with long-term observational datasets and historical temperature records. Here, I used odonates (drag- onflies and damselflies) and Sepsid scavenger flies to unravel how temperature affects development and phenology at different latitudes and elevations. The main purpose of this thesis is to provide essential knowledge on the factors driving the spatiotemporal phenological dynamics by (1) investigating how phenology changed in time and space across latitude and elevation in northcentral Europe during the past three decades, (2) assessing potential temporal changes in thermal sensitivity of phenology and (3) describing the geographic pattern and usefulness of thermal performance curves in predicting natural responses.

  • The Wing Venation of Odonata
    International Journal of Odonatology, 2019 Vol. 22, No. 1, 73–88, https://doi.org/10.1080/13887890.2019.1570876 The wing venation of Odonata John W. H. Trueman∗ and Richard J. Rowe Research School of Biology, Australian National University, Canberra, Australia (Received 28 July 2018; accepted 14 January 2019) Existing nomenclatures for the venation of the odonate wing are inconsistent and inaccurate. We offer a new scheme, based on the evolution and ontogeny of the insect wing and on the physical structure of wing veins, in which the veins of dragonflies and damselflies are fully reconciled with those of the other winged orders. Our starting point is the body of evidence that the insect pleuron and sternum are foreshortened leg segments and that wings evolved from leg appendages. We find that all expected longitudinal veins are present. The costa is a short vein, extending only to the nodus, and the entire costal field is sclerotised. The so-called double radial stem of Odonatoidea is a triple vein comprising the radial stem, the medial stem and the anterior cubitus, the radial and medial fields from the base of the wing to the arculus having closed when the basal sclerites fused to form a single axillary plate. In the distal part of the wing the medial and cubital fields are secondarily expanded. In Anisoptera the remnant anal field also is expanded. The dense crossvenation of Odonata, interpreted by some as an archedictyon, is secondary venation to support these expanded fields. The evolution of the odonate wing from the palaeopteran ancestor – first to the odonatoid condition, from there to the zygopteran wing in which a paddle-shaped blade is worked by two strong levers, and from there through grade Anisozygoptera to the anisopteran condition – can be simply explained.

  • Commonwealth Listing Advice on Alpine Sphagnum Bogs And
    Advice to the Minister for the Environment, Heritage and the Arts from the Threatened Species Scientific Committee (the Committee) on Amendments to the List of Ecological Communities under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) 1. Summary of conservation assessment by the Committee This advice follows the assessment of information provided by a nomination to list the Alpine Bog Community as a threatened ecological community. The nomination was made available for public exhibition and comment for a period of two months. The Committee had regard to all public and expert comments that were relevant to the survival of the ecological community. The Committee judges that the ecological community has been demonstrated to have met sufficient elements of: • Criterion 2 to make it eligible for listing as endangered; • Criterion 3 to make it eligible for listing as endangered; and • Criterion 4 to make it eligible for listing as endangered. 2. Name of the ecological community A nomination was received for the Alpine Bog Community. Alpine bogs are commonly found in the vicinity of alpine fens, and have been identified as being dependent on these (VSAC, 1991a). In order to make identification easier in the field, to recognise the importance of Sphagnum species to alpine bogs, and to acknowledge the interdependency of alpine bogs, fens and the natural drainage lines that connect them, the Committee recommends that the name of the ecological community be changed to the “Alpine Sphagnum Bogs and Associated Fens” ecological community. 3. Description The Alpine Sphagnum Bogs and Associated Fens ecological community generally has sharp boundaries and is easily delineated from other alpine vegetation communities.

    White Box-Yellow Box-Blakely’s Red Gum Grassy Woodland and Derived Native Grassland Ecological Community Species List White Box-Yellow Box-Blakely’s Red Gum Grassy Woodland and Derived Native Grassland Ecological Community Species List This species list is designed to provide information about plant species that can be found in the White Box-Yellow Box-Blakely’s Red Gum Grassy Woodland and Derived Native Grassland ecological community listed under the Environment Protection and Biodiversity Conservation Act 1999. The species list was developed to complement the Listing Information Guide, and should be read in that context. It provides information on scientific and common names of the species, the kind of plant the species is, whether it is an ‘important’ species for the purposes of this ecological community and whether it is exotic or native, perennial or annual. The list is not exhaustive and not all of the species listed will occur in every patch of White Box-Yellow Box-Blakely’s Red Gum Grassy Woodland and Derived Native Grassland. If there are any species that you think should be added to the list, removed from the list, or that are categorised incorrectly, please contact [email protected]. As such, this document may change over time and you should check that you are referring to the most recent version of the list. Caveat: This list has been compiled from a range of sources. While reasonable efforts have been made to ensure the accuracy of the information, no guarantee is given, nor responsibility taken, by the Commonwealth for its accuracy, currency or completeness.

  • Reconstructing the Basal Angiosperm Phylogeny: Evaluating Information Content of Mitochondrial Genes
    55 (4) • November 2006: 837–856 Qiu & al. • Basal angiosperm phylogeny Reconstructing the basal angiosperm phylogeny: evaluating information content of mitochondrial genes Yin-Long Qiu1, Libo Li, Tory A. Hendry, Ruiqi Li, David W. Taylor, Michael J. Issa, Alexander J. Ronen, Mona L. Vekaria & Adam M. White 1Department of Ecology & Evolutionary Biology, The University Herbarium, University of Michigan, Ann Arbor, Michigan 48109-1048, U.S.A. [email protected] (author for correspondence). Three mitochondrial (atp1, matR, nad5), four chloroplast (atpB, matK, rbcL, rpoC2), and one nuclear (18S) genes from 162 seed plants, representing all major lineages of gymnosperms and angiosperms, were analyzed together in a supermatrix or in various partitions using likelihood and parsimony methods. The results show that Amborella + Nymphaeales together constitute the first diverging lineage of angiosperms, and that the topology of Amborella alone being sister to all other angiosperms likely represents a local long branch attrac- tion artifact. The monophyly of magnoliids, as well as sister relationships between Magnoliales and Laurales, and between Canellales and Piperales, are all strongly supported. The sister relationship to eudicots of Ceratophyllum is not strongly supported by this study; instead a placement of the genus with Chloranthaceae receives moderate support in the mitochondrial gene analyses. Relationships among magnoliids, monocots, and eudicots remain unresolved. Direct comparisons of analytic results from several data partitions with or without RNA editing sites show that in multigene analyses, RNA editing has no effect on well supported rela- tionships, but minor effect on weakly supported ones. Finally, comparisons of results from separate analyses of mitochondrial and chloroplast genes demonstrate that mitochondrial genes, with overall slower rates of sub- stitution than chloroplast genes, are informative phylogenetic markers, and are particularly suitable for resolv- ing deep relationships.

  • Rare Or Threatened Vascular Plant Species of Wollemi National Park, Central Eastern New South Wales
    Rare or threatened vascular plant species of Wollemi National Park, central eastern New South Wales. Stephen A.J. Bell Eastcoast Flora Survey PO Box 216 Kotara Fair, NSW 2289, AUSTRALIA Abstract: Wollemi National Park (c. 32o 20’– 33o 30’S, 150o– 151oE), approximately 100 km north-west of Sydney, conserves over 500 000 ha of the Triassic sandstone environments of the Central Coast and Tablelands of New South Wales, and occupies approximately 25% of the Sydney Basin biogeographical region. 94 taxa of conservation signiicance have been recorded and Wollemi is recognised as an important reservoir of rare and uncommon plant taxa, conserving more than 20% of all listed threatened species for the Central Coast, Central Tablelands and Central Western Slopes botanical divisions. For a land area occupying only 0.05% of these divisions, Wollemi is of paramount importance in regional conservation. Surveys within Wollemi National Park over the last decade have recorded several new populations of signiicant vascular plant species, including some sizeable range extensions. This paper summarises the current status of all rare or threatened taxa, describes habitat and associated species for many of these and proposes IUCN (2001) codes for all, as well as suggesting revisions to current conservation risk codes for some species. For Wollemi National Park 37 species are currently listed as Endangered (15 species) or Vulnerable (22 species) under the New South Wales Threatened Species Conservation Act 1995. An additional 50 species are currently listed as nationally rare under the Briggs and Leigh (1996) classiication, or have been suggested as such by various workers. Seven species are awaiting further taxonomic investigation, including Eucalyptus sp.

PhytoKeys 38: 89–99. doi: 10.3897/phytokeys.38.6504 Abstract The new speciesCissampelos arenicola M. Nee & R. Ortiz, from the Bolivian and Paraguayan Chaco is described, its affinities are discussed, and its preliminary conservation status is evaluated. The species is at present known from 13 collections from sand dunes or dry forests. Cissampelos arenicola is distinguished from all other American species in the genus by its ovate- to subreniform-trilobed leaves, 8-locular synan- dria, and relatively large, and scarcely ornamented endocarps. The most common perianth condition in the pistillate flowers of Cissampelos is one sepal and one antesepalous petal, and while these may vary in number, they are always found adaxial to the carpel, and although the southern African taxon called Cissampelos capensis, whose generic position is uncertain, superficially resembles Cissampelos arenicola, its sepals and petals are consistently lateral to the carpel and not adaxial.
